Mark Cuban believes signing Deron Williams may not have been the best move.

"I don't want to pick on Deron Williams because he's a great, great, great player, and so it's not necessarily him, per se," Cuban said. "The conversation we had going back and forth -- and obviously the decision was to go for him -- but the conversation was, 'OK, once you add $17.1 million in salary to what we'd have with Dirk (Nowitzki) and Trix (Shawn Marion), then what do you do?' That's your squad. And it's not just your squad for this year. It's your squad for next year other than the $3.3 million mini midlevel.

"So that was a challenge that we had because we want to win, and everybody talks about Dirk's window. Well, not only would it have been difficult to add players, then it also would have been difficult to trade players, and in reality that was the same problem that Deron had. Because he looked and saw the same thing and said, 'OK, now what are you going to do?'"

Williams was reportedly unsure about the Mavericks’ future, choosing instead to sign a five-year, $98 million deal with the Nets.
